Individuals with bipolar disorder (BD) show heterogeneity in clinical, cognitive, and daily functioning characteristics, which challenges accurate diagnostics and optimal treatment. A key goal is to identify brain-based biomarkers that inform patient stratification and serve as treatment targets. The objective of the present study was to apply a data-driven, multivariate approach to quantify the relationship between multimodal imaging features and behavioral phenotypes in BD.

Objective: A proportion of patients with bipolar disorder (BD) manifests with only Unipolar mania (UM). We conducted a follow-up study of patients diagnosed with Unipolar mania and compared them as a group if they had a mild depressive episode with those who did not.
Method: 248 subjects were prospectively followed-up to 15 years.
Pharmacokinetics and Pharmacodynamics of an Innovative Psychedelic N,N-Dimethyltryptamine/Harmine Formulation in Healthy Participants: A Randomized Controlled Trial.

Background: Recent interest in the clinical use of psychedelics has highlighted plant-derived medicines like ayahuasca showing rapid-acting and sustainable therapeutic effects in various psychiatric conditions. This traditional Amazonian plant decoction contains N,N-dimethyltryptamine (DMT) and β-carboline alkaloids such as harmine. However, its use is often accompanied by distressing effects like nausea, vomiting, and intense hallucinations, possibly due to complex pharmacokinetic/pharmacodynamic (PK-PD) interactions and lack of dose standardization.

Familial hemiplegic migraine type 2 results from pathogenic variants in the gene, which encodes for a catalytic subunit of sodium/potassium ATPase. This extremely rare autosomal dominant disorder manifests with a spectrum of symptoms, most commonly pure hemiplegic phenotype, epilepsy, and/or intellectual disability. In this study, we detail the clinical features and genetic analysis of nine patients from a large family spanning four generations, with all carrying a previously unreported likely pathogenic variant, p.
